DNA testing is an important tool for identifying and tracking endangered species. For instance, scientists can use DNA to check that fish served in restaurants is correctly labeled. Sometimes, restaurants mistakenly serve endangered fish—periodic DNA tests can help prevent this. But what if the animal in question is still alive? The answer may be eDNA, or environmental DNA, which can be taken from the soil or water in which an animal lives without disturbing the animal itself. Gathering eDNA is less stressful to animals than taking DNA samples, since scientists can simply take samples of water from its environment.

Question 9

Completed in 1762, the Trevi Fountain is a popular tourist attraction in Rome, Italy. Over the years, however, the fountain has aged and cracked. In 1998, the city responded by having workers scrub the stonework and repair the cracks. By 2012, the fountain needed more serious repairs: pieces of it were crumbling. This time, the Italian fashion house Fendi provided the funds needed to restore the fountain. In 2015, the work was completed, and the fountain opened once again.

Question 10
10. Select the best evidence to support the statement that the first electric cars had several drawbacks.

In the late 1800s there was a race to invent the "horseless carriage." Coal was too heavy to use for fuel, so people tried other things, including natural gas, gunpowder, and something we now think of as modern: batteries. For a while, batteries seemed to be the answer—by 1897 New York City had a fleet of electric taxis, and in 1899 the world land speed record of 68 miles per hour (109 kilometers per hour) was set in an electric car. But the batteries were heavy and cumbersome relative to the power they supplied, and they burned out if you tried to go too fast.
